SPECIFICATION forming part of Letters Patent No. 252,703, dated January 24, 182 2.

Application filed July 23, 1881. (X0 model.) Patented in England July 10, 1879.

To all whom it may concern:

Be it known that I, HENRY SCOTT, of Birmingha-m England, have invented certain new and use't'ul Improvements in Fire- Arms, of which the following is a specification.

My invention has reference to breech-loadi ng smal'l-arms of thekind commonly called .tdrop-down guns; 'and'the invention consists in the arrangements or combinations of parts, hereinafter dcscribed,f0r eockiugthe concealed or internal hammers of the said guns, and also the arrangen'ient ot' the parts, hereinafter described, of safety apparatus for preventing the accidental discharge of the guns.

In the accompanying drawings, Figure l is a vertical longitudinal section of the breech portion of a drop-down gun containing cocking mechanism according to my invention. Fig. 2 is a plan view of the body of the gun. Fig. 3 is a transverse vertical section of the same, taken beh nd the break-off, with the internal hammers omitted. Fi 4; represents a part of the cocking mechanism detached. Figs. 5 and 6 are-longitudinal sections of the gtnnsliowing the safety appliances. Fig. 7 is a detail. Fig. 8 isa detail view, showing the position of the. parts at the. moment the hammer arrives at full-co: h. Fig. 9 is adetail view of-th'c hannuer..

Similar letters of reference indicate corrisponding parts.

In the drawings, a (t are the internal hammers, carried by the lock plates 1) 11, let into the sides of theb'ody. cis the cross-axis turn- J ing in the said body. The axis 0 has at each end a cocking-arm, d, the ends of the arms being provided with shoulders d (1 for engaging with the shoulders a a on the internal hammers, a a.

0n the middle of cross-axis ca vertical arm, c, is fixed, the said arm extending upward to the under side of the tang of the break-oft. Under the said tang is a slide, f, worked by the thumb-plate g on the upper side of the tang, and capable of motion to and from the break-oil". The front end of the slide f. is jointed at h to the upper end of the vertical arm 0. When the slide f is in the normal or forward position represented in the drawings the cocking-arms d d lie in recesses in the side of the body and are out of contact with the cooked hammers (la, as represented, and the said hammers may fail to discharge the gun. After the gun ha been discharged the side shoulders, (I? (1. on the hammers a are in contact with the side shoulders, 11 11 on the ends of the cockiug arms d. (I.

In order to cock the gun at'ter tiring, the thumb-plate g of the slidefis moved back toward the butt-end ot' the gun. lhe said slide, acting through the vertical arm givesmotion to the cross-axis c, and the cocking-arms d d on the said axis are thereby made to throw back the hammers to full-cock by the shoulders (I d of the said arms beariugagainst the shoulders 0b a? of the hammers.

The hammers are etained in their cocked positions by the sear mechanism carried by the locleplates b b, as usual. ()n releasing the thumb-plate g of the slide it is returned by the locking-bolttothe normal position shown, and

tho cocking-arms d d are at the sametime removed from the cooked hammers, and the gun is ready to be dischai'ged. The lockingbolt iis worked by the middle vertic i1 ariu,e, which passesthrough it, so that the motion of the slidej'to cook the hannners at. the time withdraws the locking-b ilt'i to 'uut'asten the barrels. A spring gives the back or snapping action to the lock-bolt '2 and the back motion of the said bolt causes the return ot'slidefnud cocking-arms d (l to their normal positions. I have represented hamnu-rs having curved noses for striking directly on the cartridges, but fiat hammers acting upon strikers may be used with my improved cocking mechanism.

Instead of-operatiug the cocking-arms d d by means of a slide,f as described and illustrated, the said arms may b5 worked by a hand-lever on the side or under side of the gun. In this case .the middle arm, 0, is dispensed with, and the hand-lever is furnished with a square hole which takes upon a square part of the cross-axis c, carrying the eockingarms d d, or a hand-lever on the tang having a side or horizontal motion may be. usrd. In this modification the axis of the hand-lever is made to operate upon a short arm at the middle of the axis of the cocking-arms to move the said cocking-axis through the required angle, to cause the said cocking-aims to hit the hammers to full-cock.

Instead of cockinglthe gun by hand it may is the hand-leveron the tang, by which the be cocked'hy'tli' iisingofgthe breech ends of locking'bolt is withdrawn, the said hand-lever the barrelsforreloadingthegun. In this case having a side'or horizontal motion.
